DEAR CUSTOMER, Thanks a lot for your interest in Zedler testing services.

With precise, innovative and reliable testing systems we provide tailor-made solutions for nearly any testing tasks in state-of-the-art mechanical testing of bicycles and bicycle components. For many years, we have been one of the leading suppliers of testing services and systems that you can find in the testing laboratories of the trend-setting bicycle manufacturers and magazines.

The testings of our PERFORMANCE series are mainly designed to test bicycle frames, forks and components for stiffness and geometry. They allow precise statements about the riding behaviour without time consuming assembly and test rides in different terrains.

Measurement results of the PERFORMANCE testing systems series put into numbers riding char- acteristics of bicycles and their components. You cannot only measure the frameset’s resistance to dangerous wobbling during a fast ride or the swaying of trekking bikes under load, but also the bottom bracket stiffness to entirely convert the rider’s power during strong pedalling into propul- sion. The comfort that characterizes the frame and the fork is measured in millimetres of the spring travel. The tests of the lateral wheel and fork stiffness not only indicate whether the brake pads of bicycles with rim brakes drag along the rim, but also whether the front wheel directly responds to the rider’s steering pulse. Due to the faster moved e-bikes/pedelecs, the criteria of active driving safety, the bicycle performance, are increasingly important beyond the field of sports bicycles. With our stiffness measurements you are in a position to check whether the quality of a fabrication batch of carbon components fully complies with your specifications and to get an idea of the deviations.

The testings of the PERFORMANCE series deliver accurate and thus absolutely comparable measurements that even Europe’s leading bicycle magazines take as basis for evaluation. We are proud to report that the values obtained on our machines are often taken as reference values.

I am absolutely confident that our testing results will be a valuable support in the development of your products and wish you good luck and success. I welcome your feedback. Feel free to send us your inquiries, improvement suggestions or criticism.

YOUR ADVANTAGES AT A GLANCE: Development-accompanying measurements that are comparable to the products of other market players/competitors Measured values of testing standards comparable to the values of the German magazines BIKE, E-BIKE, Freeride, TOUR and Trekkingbike No negative surprises in the case of magazine tests Communication with your suppliers or customers on the basis of measurements that are accepted worldwide The opportunity to produce consistent product quality due to sample checks As a result you have many satisfied customers with bicycles that have an excellent riding behaviour and an outstanding performance YOUR TEST REPORT INCLUDES: Measurement results gained from technically mature, reliable and calibrated Zedler testing systems made in Germany Depending on the component to be tested, benchmark charts comprising up to 500 data sets with products of many market players/competitors FURTHER TESTING SERVICES – SAFETY AND QUALITY: Besides the PERFORMANCE tests we offer further testing services in our laboratory: Framesets, bicycle assemblies and individual components can be tested with regard to overload, impact strength as well as fatigue behaviour. The newly developed bicycle testing systems simulate typical riding situations, special events and foreseeable inappropriate use and misuse in realistic clamping. To determine reasonable torque values and mounting specifications for assemblies instead of relying upon the instructions of the screw manufacturers, is a first, very important step towards the minimi- zation of failures in service. Further examinations and measurements comprise the entire field of “precision” and “bicycle fit” as well as coating tests and functional tests.

TESTING SYSTEMS − SALE: We not only offer testing services in our company own testing laboratory in Ludwigsburg, but also supply the testing systems.

TEST PROCEDURE The tests are performed in the elastic range and therefore non destructive. The products can be reused after the test. DURATION OF THE TESTING SERVICES In general, PERFORMANCE tests will be performed within five working days. Please place your testing order in good time. Rush orders including delivery of the results within 48 hours, will be invoiced at an extra charge of 25 %. Instant orders of PERFORMANCE testings, when the component is supplied and collected directly, will be invoiced at an extra charge of 50 %. In these cases the results will be supplied by email directly following the measurements. Please get in touch with us to discuss the details! WHAT HAPPENS TO THE TEST PIECES In principle, all test pieces are returned. The principal is obliged to store or file the respective test sample after it has been returned by Zedler GmbH for a period of time of eleven years at least in view or preserving evidence. All disadvantages that arise from the infringement of the obligation to store shall be at the expense of the principal.
